Flanking transmission of a double-plate system with joists and cavities

Brunskog, Jonas LU (2004) 18th International Congress on Acoustics In 8th International Congress on Acoustics
Abstract
The work with development of new building systems is intensive. These systems are often related to lightweight constructions, and developed to be used in load-bearing structures and dwellings. One of the main drawbacks of this type of building systems is often the sound insulation. Lightweight walls and floors are often designed as frameworks of studs with plates on both sides - a double-plate structure. The flanking transmission is often the limiting aspect for the total sound insulation of such a structure. A prediction model for flanking transmission of lightweight building structures is thus under development. In the present paper the structural transmission loss when a double-plate structure meets a discontinuity is primary studied... (More)

The model is analytic and deterministic and makes use of a spatial Fourier transform wave approach for periodic structures (Less)
